The internet's favorite twins pose for photo shoot with their mom to announce new sibling

At only 4 years old, Alexis and Ava McClure are social media celebrities. The adorable twins are probably the hardest-working toddlers in the entertainment business: They video-blog, have a clothing and accessory line, and model. With their more than 1.1 million Instagram followers and almost 600,000 YouTube subscribers, the sisters’ hard work is clearly paying off.

Their supercute viral videos have landed them in internet superstardom, and a recent announcement has created even more buzz for the twins. Their mom, Ami Dunn McClure, 36, who’s originally from Nigeria, posed in a photo shoot with her famous children, sharing the big news that the biracial family is welcoming a baby boy later this year.

The twins’ father, Justin McClure — who is the photographer and videographer behind the girls’ shoots — also posted a heartwarming message announcing the soon-to-be baby boy. “I’m so grateful to have this life with my daughters and soon to be son,” he wrote.

The McClure twins’ fans are celebrating the news that another McClure baby is on the way.
